Answer:
C) never
Step-by-step explanation:
It means the system of equations is true for all values of the variables that satisfy one of the equations. The other equation is identical, so any values that satisfy the first equation will also satisfy the second equation.
There will be an infinite number of solutions. There will never be no solution.

<u>Example</u>:
x + y = 4
-x -y +4 = 0
Adding the two equations gives ...
(x +y) +(-x -y +4) = (4) + (0)
4 = 4
The solutions to this system are all values of x and y such that x+y=4. There are an infinite number of such solutions.
Answer:
-9
Step-by-step explanation:
use an equation to solve this
consecutive means in succession, one after the other
since they're odd, both numbers have to be odd
let x be the first number
x+x+2=-20
+2 because if you only +1, one of the numbers would be even
2x+2=-20
-2. -2
2x=-22
x=-11
the smaller would be -9 since we are adding x and x+2 together

What Do you mean 6 passwords?
This is an arithmetic sequence with first term 2 and common difference 7. The general term a[n] can be written as
a[n] = 2 +7(n -1)
or
a[n] = 7n -5
